Motorway doesn't (or shouldn't) imply any access restrictions, just that 
it doesn't have at-grade intersections (save for emergency vehicle, or 
rarely, extremely rural range access).  28 states allow all modes on all 
roads, for example, so it's not reasonable to make any access assumptions 
based on the highway=motorway tag.  Oregon, Washington and British 
Columbia are good examples of where this applies.

A few states, usually those with turnpikes, allow bicycles on expressways 
(trunks: motorways with at-grade intersections) and freeways (toll-free 
motorways), but not on turnpikes (toll motorways).
